Let's divide 286431 by 29
The aim is to understand the frequency of 29 in 286431.

Moving on to step 1:
29 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 29

Step 2:
28 divided by 29 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 29

Step 3:
When dividing 286 by 29, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 261 from 286 leaves us with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 29

Going ahead to step 4:
29 can be fit into 254 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 98.0
Subtracting 232 from 254 leaves us with 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 29

On to step 5:
When dividing 223 by 29, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 987.0
If we subtract 203 from 223, we get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 29

Going ahead to step 6:
29 can be fit into 201 6 times, resulting in a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 9876.0
Subtract 174 from 201 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
270 divided by 29 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 9876.9
The remainder is 9 after subtracting 261 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
When dividing 90 by 29, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 9876.93
Deduct 87 from 90 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
29 can be fit into 30 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 9876.931
The remainder is 1 after subtracting 29 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
29 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 9876.931
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
29 can be fit into 100 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 9876.93103
Subtract 87 from 100 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
29 can be fit into 130 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 9876.931034
If we subtract 116 from 130, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
If we divide 140 by 29, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 9876.9310344
Subtract 116 from 140 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 9876.9310344 with a balance of 2.4e-07.
